Additional Information
The fetal pole is a crucial structure in the development of the embryo, as it plays a key role in the formation of the neural tube and the development of the brain and spinal cord. As the embryo grows, the fetal pole will eventually give rise to the placenta, umbilical cord, and amniotic sac.
The fetal pole is typically visible on ultrasound scans from around 5-6 weeks into pregnancy, and its presence is an important indicator of a healthy pregnancy. Abnormalities in the development of the fetal pole can be indicative of potential pregnancy complications or chromosomal abnormalities.
